Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

So, this indicates that you may have stumbled across a bug in 
drbd-0.6.13 .

  If this were drbd-0.7.x I would try to reproduce that bug, and to fix 

  If you were a paying LINBIT customer I would try to reproduce that
  bug and try to fix it...
